TECHNICAL FIELD

The present invention relates to the field of perfumery. Moreparticularly, it concerns the use of some phenol esters, as definedherein in the description, as perfuming ingredients. Moreover, thepresent invention comprises also the embodiments wherein the invention'scompound is part of a perfuming composition or of a perfuming consumerproduct.

PRIOR ART

Some phenol esters are know from the prior art as having odor or tasteof potential interest for the perfumery industry. One may cite thoselisted in reference texts such as the book by S. Arctander (Perfume andFlavor Chemicals, 1969, Montclair, N.J., USA), which are the No 1164,2491, 2499, 2500, 2504, 2508 and 2607. All these materials arecharacterized by notes of the sweet/honey/balsamic and/or floral and/orfruity type.

The phenyl 3-methyl-butanoate has been reported (see J. Chem. Soc, 1915,110, 33) as having an ethereal (i.e. floral sweet) and unpleasant odor.

Some of the invention's compounds are known from the prior art, but noneof them has been reported or suggested as having potentially an odor oreven less as being potentially a perfuming ingredient. For example, thephenyl 4-pentenoate is mentioned, e.g. see J. Am. Chem. Soc 2007, 129,12662, as intermediate in a radical process to obtain piperidinones. Thephenyl 4-methyloctanoate is also known in the prior art, see CN10127274891 or CA 2008:1196283, and said ester is mentioned as achemical intermediate in the synthesis of some derivatives of the3-methylheptanoic acid.

However as mentioned above, these prior art documents do not report orsuggest any organoleptic properties of the compounds of formula (I), orany use of said compounds in the field of perfumery.

DESCRIPTION OF THE INVENTION

We have now surprisingly discovered that a compound of formula

-   -   wherein R represents a C₂₋₆ branched alkyl group or a C₂₋₆        linear or branched alkenyl group or cyclopropyl containing        hydrocarbon group;        can be used as perfuming ingredient, for instance to impart        animal odor notes of the castoreum and/or costus type.

For the sake of clarity, by the expression “cyclopropyl containinghydrocarbon group”, or the similar, it is meant the normal meaningunderstood by a person skilled in the art, i.e. a hydrocarbon groupcomprising a cyclopropyl moiety.

According to a particular embodiment of the invention, R represents a C₃or C₆ branched alkyl group or a C₂₋₄ linear or branched alkenyl group orcyclopropyl containing hydrocarbon group, like vinyl or cyclopropyl.According to a particular embodiment of the invention, R represents aC₂, C₃ or C₄ linear or branched alkenyl group.

According to a particular embodiment of the invention, R represents aC₂, C₃ or C₄ linear or branched alk-1-eneyl group, such as a vinylgroup.

As specific examples of the invention's compounds, one may cite, asnon-limiting example, phenyl 4-pentenoate, which possesses a fresh andnatural animal/castoreum note, reminding very closely of the naturalCastoreum oil. In fact, this compound is a valid substitute for natural,or synthetic reconstitutions, of castoreum oil the uses of which aremore and more restricted due to various reasons.

As other example, one may cite phenyl 4-methyloctanoate, which has ananimal/costus note with a leathery aspect.

As other specific, but non-limiting, examples of the invention'scompounds, one may cite the following ones in Table 1:

TABLE 1 Invention's compounds and their odor properties Compoundstructure and name Odor notes

Costoreum, civette, slightly ciste.

Costus, slightly animal, butyric and fruity notes.

According to a particular embodiment of the invention, the compounds offormula (I) are phenyl 4-pentenoate or phenyl(E)-hex-4-enoate.

In fact, the invention's compounds are lacking, or do not possesssignificant floral notes. In addition, the odor of the invention'scompounds is also lacking, or does not possess significant, pungentand/or honey and/or floral type notes, which are also characteristic ofsome of the prior art compounds. Said differences lend the invention'scompounds and the prior art compounds to be each suitable for differentuses, i.e. to impart different organoleptic impressions.

As mentioned above, the invention concerns the use of a compound offormula (I) as perfuming ingredient. In other words, it concerns amethod to confer, enhance, improve or modify the odor properties of aperfuming composition or of a perfumed article, which method comprisesadding to said composition or article an effective amount of at least acompound of formula (I). By “use of a compound of formula (I)” it has tobe understood here also the use of any composition containing a compound(I) and which can be advantageously employed in perfumery industry.

Said compositions, which in fact can be advantageously employed asperfuming ingredients, are also an object of the present invention.

Therefore, another object of the present invention is a perfumingcomposition comprising:

-   i) as perfuming ingredient, at least one invention's compound as    defined above;-   ii) at least one ingredient selected from the group consisting of a    perfumery carrier and a perfumery base; and-   iii) optionally at least one perfumery adjuvant.

By “perfumery carrier” we mean here a material which is practicallyneutral from a perfumery point of view, i.e. that does not significantlyalter the organoleptic properties of perfuming ingredients. Said carriermay be a liquid or a solid.

As liquid carrier one may cite, as non-limiting examples, an emulsifyingsystem, i.e. a solvent and a surfactant system, or a solvent commonlyused in perfumery. A detailed description of the nature and type ofsolvents commonly used in perfumery cannot be exhaustive. However, onecan cite as non-limiting example solvents such as dipropyleneglycol,diethyl phthalate, isopropyl myristate, benzyl benzoate,2-(2-ethoxyethoxy)-1-ethanol or ethyl citrate, which are the mostcommonly used. For the compositions which comprise both a perfumerycarrier and a perfumery base, other suitable perfumery carriers, thanthose previously specified, can be also ethanol, water/ethanol mixtures,limonene or other terpenes, isoparaffins such as those known under thetrademark Isopar® (origin: Exxon Chemical) or glycol ethers and glycolether esters such as those known under the trademark Dowanol® (origin:Dow Chemical Company).

As solid carrier one may cite, as non-limiting examples, absorbing gumsor polymers, or yet encapsulating materials. Examples of such materialsmay comprise wall-forming and plasticizing materials, such as mono, di-or trisaccharides, natural or modified starches, hydrocolloids,cellulose derivatives, polyvinyl acetates, polyvinylalcohols, proteinsor pectins, or yet the materials cited in reference texts such as H.Scherz, Hydrokolloids: Stabilisatoren, Dickungs- and Gehermittel inLebensmittel, Band 2 der Schriftenreihe Lebensmittelchemie,Lebensmittelqualitat, Behr's VerlagGmbH & Co., Hamburg, 1996. Theencapsulation is a well known process to a person skilled in the art,and may be performed, for instance, using techniques such asspray-drying, agglomeration or yet extrusion; or consists of a coatingencapsulation, including coacervation and complex coacervationtechniques.

By “perfumery base” we mean here a composition comprising at least oneperfuming co-ingredient.

Said perfuming co-ingredient is not of formula (I). Moreover, by“perfuming co-ingredient” it is meant here a compound, which is used ina perfuming preparation or a composition to impart a hedonic effect. Inother words such a co-ingredient, to be considered as being a perfumingone, must be recognized by a person skilled in the art as being able toimpart or modify in a positive or pleasant way the odor of acomposition, and not just as having an odor.

The nature and type of the perfuming co-ingredients present in the basedo not warrant a more detailed description here, which in any case wouldnot be exhaustive, the skilled person being able to select them on thebasis of his general knowledge and according to intended use orapplication and the desired organoleptic effect. In general terms, theseperfuming co-ingredients belong to chemical classes as varied asalcohols, lactones, aldehydes, ketones, esters, ethers, acetates,nitriles, terpenoids, nitrogenous or sulphurous heterocyclic compoundsand essential oils, and said perfuming co-ingredients can be of naturalor synthetic origin. Many of these co-ingredients are in any case listedin reference texts such as the book by S. Arctander, Perfume and FlavorChemicals, 1969, Montclair, N.J., USA, or its more recent versions, orin other works of a similar nature, as well as in the abundant patentliterature in the field of perfumery. It is also understood that saidco-ingredients may also be compounds known to release in a controlledmanner various types of perfuming compounds.

By “perfumery adjuvant” we mean here an ingredient capable of impartingadditional added benefit such as a color, a particular light resistance,chemical stability, etc. A detailed description of the nature and typeof adjuvant commonly used in perfuming bases cannot be exhaustive, butit has to be mentioned that said ingredients are well known to a personskilled in the art.

An invention's composition consisting of at least one compound offormula (I) and at least one perfumery carrier represents a particularembodiment of the invention as well as a perfuming compositioncomprising at least one compound of formula (I), at least one perfumerycarrier, at least one perfumery base, and optionally at least oneperfumery adjuvant.

It is useful to mention here that the possibility to have, in thecompositions mentioned above, more than one compound of formula (I) isimportant as it enables the perfumer to prepare accords, perfumes,possessing the odor tonality of various compounds of the invention,creating thus new tools for his work.

For the sake of clarity, it is also understood that any mixtureresulting directly from a chemical synthesis, e.g. a reaction mediumwithout an adequate purification, in which the compound of the inventionwould be involved as a starting, intermediate or end-product could notbe considered as a perfuming composition according to the invention asfar as said mixture does not provide the inventive compound in asuitable form for perfumery. Thus, unpurified reaction mixtures aregenerally excluded from the present invention unless otherwisespecified.

Furthermore, the invention's compound can also be advantageously used inall the fields of modern perfumery, i.e. fine or functional perfumery,to positively impart or modify the odor of a consumer product into whichsaid compound (I) is added. Consequently, a perfuming consumer productwhich comprises:

i) as perfuming ingredient, at least one compound of formula (I), asdefined above; andii) a fine or functional perfumery base; is also an object of thepresent invention.

For the sake of clarity, it has to be mentioned that, by “perfumingconsumer product” it is meant a consumer product which is expected todeliver at least a perfuming effect, in other words it is a perfumedconsumer product. For the sake of clarity, it has to be mentioned that,by “fine or functional perfumery base” we mean here a consumer productwhich is compatible with perfuming ingredients and is expected todeliver a pleasant odor to the surface to which it is applied (e.g.skin, hair, textile, or home surface). In other words, a perfumingconsumer product according to the invention comprises the functionalformulation, as well as optionally additional benefit agents,corresponding to the desired consumer product, e.g. a detergent or anair freshener, and an olfactive effective amount of at least oneinvention's compound.

The nature and type of the constituents of the fine or functionalperfumery base do not warrant a more detailed description here, which inany case would not be exhaustive, the skilled person being able toselect them on the basis of his general knowledge and according to thenature and the desired effect of said product.

Non-limiting examples of suitable fine or functional perfumery base canbe a perfume, such as a fine perfume, a cologne or an after-shavelotion; a fabric care product, such as a liquid or solid detergent, afabric softener, a fabric refresher, an ironing water, a paper, or ableach; a body-care product, such as a hair care product (e.g. ashampoo, a coloring preparation or a hair spray), a cosmetic preparation(e.g. a vanishing cream or a deodorant or antiperspirant), or askin-care product (e.g. a perfumed soap, shower or bath mousse, oil orgel, or a hygiene product); an air care product, such as an airfreshener or a “ready to use” powdered air freshener; or a home careproduct, such as a wipe, a dish detergent or hard-surface detergent.

Some of the above-mentioned consumer product bases may represent anaggressive medium for the invention's compound, so that it may benecessary to protect the latter from premature decomposition, forexample by encapsulation or by chemically bounding it to anotherchemical which is suitable to release the invention's ingredient upon asuitable external stimulus, such as an enzyme, light, heat or a changeof pH.

The proportions in which the compounds according to the invention can beincorporated into the various aforementioned articles or compositionsvary within a wide range of values. These values are dependent on thenature of the article to be perfumed and on the desired organolepticeffect as well as the nature of the co-ingredients in a given base whenthe compounds according to the invention are mixed with perfumingco-ingredients, solvents or additives commonly used in the art.

For example, in the case of perfuming compositions, typicalconcentrations are in the order of 0.1% to 10% by weight, or even more,of the compounds of the invention based on the weight of the compositioninto which they are incorporated. Concentrations lower than these, suchas in the order of 0.01% to 5% by weight, can be used when thesecompounds are incorporated into perfumed articles, percentage beingrelative to the weight of the article.

The invention's compounds can be prepared according to a methodinvolving the addition of an adequate carboxylic acid chloride tophenol, or vice versa. A person skilled in the art knows how to bestperform said reaction.
